detailed description

The technical problems, the technical solutions, and the advantages of the present invention will be more clearly described in conjunction with the accompanying drawings and specific embodiments.

In the related mobile communication system, the core network controls the user terminal (UE) location area, that is, the core level (CN level) location area, and the UE location area controlled by the core network is called TA (Tracking Area). The core network always configures a TAI list for the UE through a NAS (Non Access Stratum) message, and the UE stores the TAI list configured by the core network. When a cell (that is, the UE is in an idle state) or accesses a cell (that is, the UE is in a connected state), the UE reads a system message broadcasted by the cell air interface, obtains information from the UE, and obtains a TAI of the current cell, if the TAI is stored in the In the TAI list stored in the UE, the UE does not need to update the TAI list; if the TAI is not stored in the TAI list, the UE initiates a TAU (Tracking Area Update) process, and the NAS message through the core network Let the interaction get a new TAI list.

In a next generation mobile communication system (for example, the fifth generation mobile communication system 5G), a new mobility state may be introduced, such as RRC inactive connected (hereinafter referred to as an inactive state). When the UE is in an inactive state, the access network node releases the RRC (Radio Resource Control) connection with the UE, but still maintains the connection with the core network. Referring to FIG. 1 , FIG. 1 is a schematic diagram of an application environment provided by an embodiment of the present disclosure. As shown in FIG. 1, when the UE is in an active state, the access network node releases the RRC connection with the UE, but still maintains a connection with the core network, as shown in FIG. 1 for NG2 and NG3, NG2. Indicates the connection between the access network node and the control plane function of the core network, and NG3 represents the connection between the access network node and the user plane function of the core network. The UE is transparent to the core network when the UE is in the inactive state. That is, the core network still considers that the UE is always in the connected state. Therefore, the downlink signaling or data will reach the access network node. At this time, the access network node needs to page the UE.

Before the inactive state is introduced, the UE has only the idle state and the connected state, the UE is in the idle state location area TA, and the connected state location area is the cell. After the inactive state is introduced, a location area RNA (RAN Notification Area) of the access network level (CN level) needs to be introduced for the UE, and the RNA may include multiple cells, and the access network node may be in the RNA. A plurality of cells in the area send a notification message to page the UE. When the UE moves out of an RNA, an RNA update is needed to enable the access network node to find the UE.

The TA and the RNA are the location areas of the UEs maintained by the core network node and the access network node, respectively, and the roles thereof are such that the core network node and the access network node can perform location area tracking on the UE. When the UE is in the idle state, the core network searches for the UE by sending a paging paging message in all the cells in the TAI list area of the UE; when the UE is in the inactive state, the access network node sends in all the cells in the RNA region. The notification message notification looks for the UE.

Based on the schematic diagram of the application environment shown in FIG. 1 and the above concept, the present disclosure proposes a UE location area update method, and the UE location area update of the present disclosure will be described below in conjunction with specific embodiments. The method is described in detail. It should be noted that the schematic diagram shown in FIG. 1 is merely an example schematic diagram, and the embodiment of the present disclosure is not limited to the application environment diagram shown in FIG. 1 . The UE described in the present disclosure may be, for example, a mobile phone, a computer, a home appliance, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (Mobile). Internet Device, MID) or a terminal device such as a wearable device. It should be noted that the specific type of the UE is not limited in the embodiment of the present disclosure.

2 and FIG. 2 is a UE location area update method according to an embodiment of the present disclosure. As shown in FIG. 2, the method includes the following steps 201-202.

Step 201: The access network entity receives a location area update request message sent by the UE.

Step 202: The access network entity sends a location area update message to the UE, where the location area update message includes at least a target access network notification area RNA, and the target RNA information is used by the access network entity. The location area update request message is RNA information updated by the UE.

In an embodiment of the present disclosure, the access network entity receives a location area update request message sent by the UE, where the location area update request message may be a message carrying an RNA update request, or may be carrying an RNA update request and The message requested by the TAU. The UE may directly send a message carrying an RNA update request to the access network entity, or may directly send a message carrying an RNA update request and a TAU request to the access network entity. In some embodiments of the present disclosure, the UE may also first acquire the current state of its own, and then send a location area update request message to the access network entity according to the current state. For example, when the UE is currently in an inactive state, the UE is prohibited from initiating a TAU request, that is, when the UE is currently in an inactive state, the UE sends the carried RNA to the access network entity. Update the requested location area update request message.

The access network entity sends a location area update message to the UE after receiving the location area update request message sent by the UE. The location area update message may be a message carrying only target RNA information, or may be a message carrying the target RNA information and a target TAI list, where the target RNA information is the access network entity. The UE updates the RNA information, and the TAI list is a TAI list updated by the core network entity for the UE.

When the location area update request message sent by the UE is a message carrying an RNA update request, the access network entity further determines, according to the RNA update request, whether the TAI list of the UE needs to be updated. If the access network entity determines that the TAI list of the UE does not need to be updated, the access network entity updates the RNA information for the UE according to the RNA request to obtain target RNA information, and the access network entity Transmitting, by the UE, a location area update message carrying the target RNA information; conversely, if the access network entity determines that the TAI list of the UE needs to be updated, the access network entity may update the request according to the location area The message requests the core network entity to update the TAI list of the UE, that is, the access network entity sends a TAU request to the core network entity, and the core network entity requests the TAU according to the TAU request after receiving the TAU request.

It can be understood that, when the access network entity sends the TAU request to the core network entity, the UE identifier code of the UE is carried in the TAU request, so that the core network entity can be configured according to The identification code of the UE determines the UE and updates the TAI list for it.

When the UE sends a location area update request message carrying the RNA update request and the TAU request to the access network entity, the TAU request may be carried in a non-access stratum NAS message, the UE Transmitting, to the access network entity, the RRC message including the RNA update request and the NAS message including the TAU request, that is, the UE may send a data packet to the access network entity in a piggyback manner. The data packet includes the RNA update The requested RRC message and the NAS message containing the TAU request. The UE may also include the TAU request in an RRC message, and send the RRC message containing the RNA update request to the access network entity.

It should be noted that when the access network entity sends a location area update message including the target RNA information and the target TAI list to the UE, the access network entity may be in the core network entity. Updating the RNA of the UE according to the RNA update request before initiating the TAU request may also update the RNA of the UE according to the RNA update request after initiating the TAU request to the core network entity. Of course, the RNA of the UE may also be updated according to the RNA while initiating the TAU request to the core network entity. In some embodiments of the present disclosure, the access network entity may further update the RNA of the UE according to the RNA update request after receiving the target TAI list sent by the core network entity, or according to the The RNA update request and the target TAI list update the TAI list of the UE are not limited in the embodiment of the present disclosure.
